- Q: If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.
- Solar panels do not wear out the way machinery does. The semiconductors used give up electrons by receiving photons, and do not experience a net deficit of particles. However, if you placed a heat source such as a heat lamp too close to a solar panel, you could damage the panel by overheating it, which would denature the semiconductors or cause damage by scorching or melting. The problem would be the heat, not the light. Solar panels do have a finite life expectancy, though it is several decades under normal circumstances. The panels will eventually become scratched, warped, and dented. The electrical conductors will eventually be broken by metal fatigue as the panels heat and cool on a daily basis. So they will die of old age, but they don't wear out in an electrochemical sense.
- Q: is a wind turbine better than solar panels
- solar water heater and solar power system.
- Q: Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace
- No. Series means one thing, parallel another, and they are mutually exclusive.
- Q: Can solar panels be used to power a farm?
- Yes, solar panels can be used to power a farm. By harnessing the power of the sun, solar panels can generate electricity that can be used to run various farm operations such as irrigation systems, grain dryers, electric fencing, and even power agricultural machinery. This renewable energy source not only reduces reliance on fossil fuels but also helps farmers save on energy costs while promoting sustainability.
- Q: I want to be more green and if I get the panels will I still have a regular electric bill?
- The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
- Q: Can solar panels be used in areas with high levels of electromagnetic radiation?
- Yes, solar panels can be used in areas with high levels of electromagnetic radiation. However, it is important to ensure that the panels are properly shielded and grounded to minimize any potential interference or damage caused by the electromagnetic radiation.
- Q: How do solar panels affect roof ventilation?
- Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat absorption and helping to keep the attic space cooler. This can decrease the need for excessive ventilation and potentially lead to energy savings. However, solar panels can also obstruct the airflow on the roof, limiting the natural ventilation and potentially causing heat buildup. Therefore, it is important to consider the design and placement of solar panels to ensure proper roof ventilation is maintained.
- Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?
- The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
- Q: Can solar panels be used to charge electric vehicles?
- Yes, solar panels can be used to charge electric vehicles. By installing solar panels on rooftops or in parking lots, the energy generated from the sun can be used to charge the batteries of electric vehicles, providing a clean and sustainable source of power. This helps reduce reliance on fossil fuels and promotes renewable energy use in transportation.
- Q: How do solar panels affect the roof's structural integrity?
- Solar panels do not significantly affect the roof's structural integrity. They are typically lightweight, and their installation involves mounting them securely onto the roof without causing any damage or weakening.
